Good question. I assumed this could be an option in the nm-applet.

I can just write about the problem I wanted to fix. The time needed 
to recognize there is a new AP or an AP disappeared was just too long.
Of course if you don't have a "fast" changing network setup this is not
really problem. This is all about moving around with your laptop/device and 
if it takes 120 seconds to see there is a new AP and 360 seconds to 
remove the AP from the list is just a bit too long IHMO.

If I didn't get it completely wrong, connman uses continuously 
scanning to overcome this problem.

The patch allows to set the scan interval for each device separately.
Basically the patch just changes default behavior in NM. The
scan is still triggered through the wpa_supplicant interface.

No, it is not card specific. Okay I think you are right about
offering users too many knobs to play with. How do you propose
to "fix" my use case?
